CVE-2015-8104 (retired)

Priority
Description
The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through
4.6.x, allows guest OS users to cause a denial of service (host OS panic or
hang) by triggering many #DB (aka Debug) exceptions, related to svm.c.
Ubuntu-Description
Jan Beulich discovered that the KVM svm hypervisor implementation in the
Linux kernel did not properly catch Debug exceptions on AMD processors. An
attacker in a guest virtual machine could use this to cause a denial of
service (system crash) in the host OS.
Notes
 sbeattie> for linux kernel, only affects AMD processors (svm)
